Integration

Hi!
I'm having a bit of trouble that I hope you can please help with...
I've just installed oracle database and am now attempting to install oracle application server.

Unfortunately everytime I attempt the install I receive a:
"Install cannot connect to the database located at:
localhost:1522
Please ensure tha tthe hostname, port and service name are correct and that the database and its listener at this location are up and running."

I have tried every possible combination I can think of for the Database Connection Information, including:
127.0.0.1:1522:orasusdb
localhost:1522:orasusdb
127.0.0.1:1521:orasusdb
localhost:1521.orasusdb
127.0.0.1:1522:orasusdb.DOMAIN
localhost:1522:orasusdb.DOMAIN
127.0.0.1:1521:orasusdb.DOMAIN
localhost:1521.orasusdb.DOMAIN

and even all the combinations above with "10.6.0.74" in place of 'localhost' as when I compelted the database installation I was given the following url to access isqlplus:
http://10.6.0.74:5560/isqlplus
Which doesn't work...
But this address:
http://localhost:5560/isqlplus/
does work...

My tnsnames.ora file:
ORASUSDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orasusdb)
)
)
LISTENER_ORASUSDB =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)



My Listener.ora file:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle/product/10.2/db_1)
(PROGRAM = extproc)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
)
)


The results of tnsping localhost:1522:
Used parameter files:
/opt/oracle/product/10.2/db_1/network/admin/sqlnet.ora

Used EZCONNECT adapter to resolve the alias
Attempting to contact (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=localhost.domain))(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1522)))

The results of lsnrctl start:
